My research is focused on understanding environmental change over timescales from decades to millennia, and their significance for human society. A key theme is the development and application of tephrochronology; a dating technique based on the identification and correlation of volcanic ash layers. Tephrochronology is important because tephra layers form time-parallel marker horizons or isochrons that provide a powerful dating framework for the high-resolution spatial analysis of environmental change. It is possible to precisely relate spatial patterns of environmental change, inferred using tephras, to high resolution time series of data from ice core records and written records of historical events in order to better understand both climate change and the human dimensions of environmental change. In addition to many applications in the study of environmental change tephra (and the volcanic eruptions that produced them) may also act as agents of change, affecting climate, natural environments and human society.

A particular interest has been the use of fine-grained micro-tephra deposits. These deposits are important because they permit both increased dating resolution in areas close to volcanoes and the use of tephrochronology over very long distances. Since 1982, joint research in Iceland and the NE Atlantic region has contributed to the development of one of the world’s largest and most detailed tephrochronologies: ca. 12,000-year record including more than 300 tephras, and more than 2,000 original stratigraphic sections. Applications of tephrochronology range from dating archaeological deposits to understanding the patterns and processes of soil erosion, slope movements, glacier chronology and the study of glacier processes.
